Difficulties in teaching Use multiplication formulas to proficiently perform calculations, teaching aids, prepare oral arithmetic cards, the teaching process, sort out the preliminary understanding of multiplication, 26 multiplication formulas, 1 the meaning of multiplication and the names of the parts in the multiplication formula, there are a few stars in total, write the addition formula, and then add the addition formula Rewrite it into a multiplication formula. Say the meaning of the multiplication formula and the names of the parts. 6666246×424 or 4×624 indicate how much the sum of 4 6s is. The student carefully observes the table and asks what the multiplication formula is in each row horizontally. Compare the number of two adjacent sentences. What have you found? Look at each column vertically and look at the order of the multiplication formula table diagonally. What rules are there? The product of the same two numbers turns to see the rules of the multiplication formula table. Read the formula back to the formula. Disorganize the order. Complete the password. Question 1 on page 66. Tell the formula you used. 2. Organize and solve simple practical problems with multiplication. 1 Teaching material, page 66, p. Question 2 Students first talk about the picture and clearly identify the problem to be solved. Find out the information and data needed to solve the problem. Students independently think about the method of solving the problem. Solve the problem and communicate their own method of solving the problem. 2 Question 2 of the textbook page 67 students complete the communication and solve the problem independently Ways to exchange multiple solutions 3 Write out what can be rewritten as a multiplication formula 2222133333666666 Three open questions 1 People’s Park an adult ticket 6 yuan a student ticket 4 yuan 1 buy 4 adult tickets, how much did it cost 2 to sell 5 students How much did the ticket cost? 2 Contact someone around you and ask the question about multiplication
